FANS.

Original No. 1,354,098, dated September 28, 1920, Serial 170. 329,960, filed October 11, 1919. Application v for reissue filed August 16, 1921. Serial No. 492,851.

To all whom it may concern:

Be it known that I, MAURICE M. Gmssnn,

' a citizen of the United States, and a. resident of Charleston, in the county of Charleston and State of South Carolina, have invented certain new and useful Improvements in Fans, of which the following is a V specification.

T oppositely are journaled in bearings 5 in the arms 6' My invention relates to motor operated fans and particularly, although not necessarily,'to' ceiling fans, a purpose of my invention being the provision of a fan having means by which it is caused to continuously oscillate through a fixed arc and at the same time bodily rotated so that the path of the are continuously changes to effect a'difi'usion of the air current produced by the fan over a greater and constantly changing area.

I will describe one form of fan embodying'my invention and will then point out the novel features thereof in the claims.

In the drawings:

Figure 1 is a front view of a fan provided with the improved oscillator;

5 Figure 2 is a view at right angles .to Figure 1;

Figure 3 is a section on the line 33 of Figure 1;

Figure 4 is a vertical section through the fan mounting;

Figure '5 is a similar view of the connection between the fan mounting and the oscillator.

The'present embodiment of the invention is shown in connection with a fan composed of asuitable motor arranged within the casing 1, the fan 2 being mounted upon the motor shaft 3. This motor casing 1 has extending journal pins 4, which of a yoke whose body 7 has at its center an upstanding sleeve 8. \Vithin this sleeve there isjournaled the lower end of a hollow post 10 which secured to the ceiling or other fixed support. 'As shown more particularly in Figure 4 the post 1O is annularly grooved intermediate its ends as shownat 12, and a ball bearing 13 is arranged between theshoulder formed'at the lower end of the groove and a washer 14 which is :connected to the upper end of the sleeve '8 by screws 15 or the like. The sleeve 8 is rotatable on the hollow post 10, and the yoke and. sleeve are supported has a'base 11 capable of being the post, by means of the ball bearing The conductors 16 and. 17 which carry the current to the motor in the case '1 are connected with rings 18 and 19, respectively, which are held on the lower end of the post, the post having openings, as shown in Figure 4 through which the conductors extend to their connection with the rings,

it being understood that the said rings are insulated from the post and from each other. Brushes 20 are secured to the sleeve 8 at opposite sides thereof by means of binding posts 21, and conductors 22 and 23 lead from the binding posts to the connections of the motor. The brushes, during the rotation of the yoke, move in contact with the rings 18 and 19, completing the circuit whatever the 67-8.

In order to oscillate the motor casing on the journal pins 4 the upper end of the motor shaft 3 extends into an auxiliary casing 25 at the top of the motor casing 1. Within this casing theshaft has a worm 26 which actuates a worm gear 27 upon a horizontal shaft 28' journaled in the auxiliary casing and in an extension 29 from'the said auxiliary casing. The outer end of this shaft carries a disk 30 and av link 31 connects this disk with a fixed disk 32'supported by the adjacent arm of the yoke 6-7, the link being connected eccentrically to both disks. The arrangement is such that when the fan is rotating the shaft 28' will be driven and because the disk 32 is fixed the motor casing and the fan will be oscillated through an arc of approximately 30. With this arrangement the blast from the fan would sweep across the fioor, for instance, in a straight line in one direction. However, I provide mechanism continuously changing'the direction of this line so that the blast fro-m the fan will sweep over many lines, the saidmechanism con-;

movement of the yoke.

tinuously rotating the yoke on the hollow post 10 in one direction.

The said mechanism comprises. a ratchet wheel 33 rigid with the lower end of the hollow post 10, and a pawl 34' pivoted on an arm 35 extending radially from'the lower endof the hollow post. The arm is loosely journaled on the post to swing with-respect thereto, and the pawl is normally pressed into engagement with the ratchet wheelby a spring 36. This arm 35 also carries a de pending pin 37 which fits between the arms of a fork 38 on the upper end of an arm 39 extending radially upward from one of the journal pins 4 and rigid with the motor casing. The arrangement is such that when the motor casing oscillates the arms of the fork will move the pin in opposite directions. In one direction the pawl 34 will slip idly over the teeth of the ratchet wheel,

While in the other direction the pawl will engage the ratchet teeth, imparting intermittent movement-to the yoke 6-7.

In operation, as the fan rotates, the motor casing will be oscillated, swingmg on the journal pins 4, that is swinging on a horizontal axis when the fan is mounted on the ceiling. At each complete swing or oscillation of the motor casing the Ol6 wlll be turned about the axis of the hollow post 10 through a predetermined are, so that each sweep or oscillation of the fan will have; a different angle. Thus the sweeps or oscillations of the fan will rotate about a fixed center, namely, the axis of the post 10.

Although I have herein shown and described only one form of fan embodying invention, it is to be understood that various changes and modifications can be made herein without departing from the scope of the invention and the scope and spirit of the appended claims.
